Replaced mine with the Shelix OEM sized head last month. It runs much quieter, the planed surface is just as good as before. I went through several sets of the HSS blades and figure that the time and $$ saved will more than pay for the Shelix.
A tip for those doing the RandR...Byrd engraves their logo on each cutter. So, orient each cutter with the logo in the same place. That way, when you turn one, you'll know which and how many turns you have left.
